DETAILED DESCRIPTION OF THE INVENTION

While this invention may be embodied in many forms, there is shown in the drawings and will herein be described in detail one or more embodiments with the understanding that this disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the invention to the illustrated embodiments.

The present invention is a “zero turn radius” reel that is easy to maneuver by hand, especially changing directions and navigating tight spaces. The reel comprises a drum assembly for carrying wound product, a first (typically stationary) flange and a second (rotatable) flange attached to either end of the drum assembly. By allowing the second flange to rotate with respect to the drum assembly, an operator can easily maneuver the reel in tight spaces. There are two embodiments of the zero turn radius reel, a friction embodiment and a bearing embodiment.

First Embodiment

Referring to the attached FIGS. 1-3 and, in particular, FIG. 1, the first (friction) embodiment reel 10 comprises a drum assembly 12, a first (stationary) flange 14 and a second (rotatable) flange 16. The first flange 14 is affixed to the drum assembly 12 in stationary relationship therewith. The second flange 16 is affixed to the drum assembly 12 but can move with respect to the drum assembly 12 as explained below.

As best shown in FIG. 2, the drum assembly 12 comprises a large diameter drum 18, smaller diameter extensions 24 and drum plates 26. The drum 18 has opposing first and second ends 20, defines an axis A and is configured to receive wound product. The small diameter extensions 24 are rigidly fixed to the drum 18 and extend axially outward from each of the first and second ends 20. The annular drum plates 26 are affixed to each of the first and second ends 20.

As shown in FIG. 3 the first (fixed) flange 14 comprises a substantially cylindrical first flange center ring 28, spokes 30 and a rim 32. The flange center ring 28 may have an inner diameter slightly larger than the outer diameter of an extension 24 so that the first flange 14 can slide onto the extension 24 during assembly. The spokes 30 extend radially outward from the flange center ring 28 and have distal ends. The rim 32 is affixed to the distal ends of the spokes 30.

Referring again to FIG. 1, the first flange 14 is affixed to the drum assembly 12, preferably in stationary relationship therewith. For example, the flange center ring 28 (obscured in FIG. 1) may be rigidly affixed (such as by welding) to the extension 24. Alternatively or in addition, the spokes 30 may be affixed (such as by welding) to the drum plate 26. An outer plate 34 may be mounted on the extension 24 to capture the first flange 14. The outer plate 34 may be welded or otherwise affixed to the extension 24.

As shown in FIG. 4, the second (rotatable) flange 16 comprises a low friction center ring 38, spokes 30, a rim 32 and fastener receiving plates 40. The center ring 38 has a diameter slightly larger than the drum extension 24 so that center ring 38, and thus the second flange 16, can slide onto the extension 24 during assembly and rotate with respect to the extension 24 during use. The spokes 30 extend radially outward from the center ring 38 and have distal ends. The rim 32 is affixed to the distal ends of the spokes 30.

The second flange 16 further comprises a plurality of radially arranged, preferably arcuate, fastener receiving plates 40, each fastener receiving plate 40 configured to fit between adjacent spokes 30. The fastener receiving plates 40 may be affixed, as by welding or other means, to the center ring 38 and/or the spokes 30.

Referring again to FIG. 1, the reel 10 further comprises an annular outer plate 42 that slides over the extension 24 so that the second flange 16 is captured between the outer plate 42 and the drum plate 26. The outer plate 42 may be welded or otherwise affixed to the extension 24. The outer plate 42 has at least one opening 43 therein for receiving fasteners 46. A locking ring 44 is slid over the extension 24 and has at least one opening 45 therein for receiving the fasteners 46. When assembled, the openings 43 in the outer plate 42 align with the openings 45 in the locking ring 44 and with openings 41 in the plates 40.

The fasteners 46 may be bolts or, preferably, spring loaded pins. The fasteners 46 have two positions. In a first (locked) position the fasteners 46 extend through the openings 45 in the locking ring 44, the openings 43 in the outer plate 42 and into the openings 41 in the plates 40 to secure the second flange 16 in stationary relationship to the extension 24. In a second (open) position, the fasteners 46 do not extend into the openings 41 in the plates 40, thereby allowing the second flange 16 to rotate with respect to the extension 24.

The second flange 16 can be locked in multiple positions with respect to the drum assembly 12 because of the multiple sets of openings 41 in the fastener receiving plates 40.

In a variation, in place of the openings 41 in the fastener receiving plates 40, holes may be formed in the spokes and used to receive the fasteners 46, eliminating the need for the fastener receiving plates 40.

Second Embodiment

Referring to FIG. 5, the second (slewing ring bearing) embodiment 110 comprises a drum assembly 112, a first (stationary) flange 114, a second (rotatable) flange 116 and a slewing ring bearing 144 (obscured in FIG. 5) to allow rotational movement of the second flange 116 with respect to the drum assembly 112.

FIGS. 6 and 7 are partial exploded perspective views of the reel 110 of FIG. 5 taken from different perspectives. The drum assembly 112 comprises a drum 118, a small diameter extension 124 (see FIG. 7) and drum plates 126. The drum 118 has opposing first and second ends 120, 122 and is configured to receive wound product. As shown in FIG. 7, the extension 124 extends axially outward from the first end 120. The drum plates 126 are affixed to the first and second ends 120, 122.

The first (stationary) flange 114 may be rigidly attached to the drum 118 in any suitable manner. For example, like the first flange 14 of the first embodiment, the first flange 114 of this second embodiment may comprise a flange center ring (not shown in the figures, but similar to the flange center ring 28 shown in FIG. 3) having an inner diameter slightly larger than the outer diameter of the extension 124 so that the first flange 114 can be mounted over the extension 124. The first flange 114 further comprises spokes 130 extending radially outward from the flange center ring and having distal ends and a circular rim 132 affixed to the distal ends of the spokes 130. The flange center ring may be welded to the extension 124 and the spokes 130 may be welded to the drum plate 126. An annular outer flange plate 134 may be mounted on the extension 124 on the side of the first flange 114 away from the drum 118 to capture the first flange 114 therebetween.

The second (rotatable) flange 116 is capable of rotational movement with respect to the drum assembly 112, and comprises an outer ring 138, spokes 130 extending radially outward from the outer ring 138 and having distal ends, and a rim 132 affixed to the distal ends of the spokes 130.

The second flange 116 also comprises an inner ring or hub 140 and an outer plate 142. The hub 140 is concentric with but has a diameter smaller than the outer ring 138. The hub 140 may slip into an opening in the outer plate 142 and may be configured to receive a winder. The outer plate 142 may be welded or otherwise affixed to the outer ring 138 and hub 140.

FIG. 8 is a close up partial exploded perspective view of a portion of the reel 110 of FIG. 5 showing in greater detail the mechanism for rotating the second flange 116 independently of the drum 118, with the second flange outer plate 142 removed to better show the slewing ring bearing 144. The slewing ring bearing 144 comprises an annular stationary race 146, so named because it is stationary with respect to (that is, rigidly affixed to) the drum assembly 112, and an annular rotatable race 148, so named because it can rotate with respect to the drum assembly 112. Each race 146, 148 may define fastener openings. The stationary race 146 and the rotatable race 148 are concentric and are configured to rotate independently of each other. The stationary race 146 may be affixed to the drum plate 126 as with bolts.

As perhaps best shown in FIG. 7, the second flange outer plate 142, and thus the second flange 116, is mounted to the rotatable race 148 with fasteners 149. For example, the fasteners 149 may be bolts that extend through openings 143 in the outer plate 142 and into openings 147 in the rotatable race 148.

Referring again to FIG. 8, the hub 140 may extend partly within the rotatable race 148 and there may be a gap between the hub 140 and the rotatable race 148. The drum plate 126 may fit within the outer ring 138 but has a smaller diameter so that the outer ring 138 and thus the flange 116 can rotate with respect to the drum plate 126 to allow free rotational movement of the second flange 116 relative to the drum assembly 112.

The reel 110 may further comprise at least one locking assembly 150 for locking the second (rotatable) flange 116 to the drum assembly 112. The locking assemblies 150 are mounted to the reel 110 and moveable between a locked configuration in which the second flange 116 is mounted to the drum assembly 112 in fixed relationship therewith, and an unlocked configuration in which the second flange 116 is freely rotatable with respect to the drum assembly 112.

Each locking assembly 150 may comprise a threaded outer block 152 mounted to the outer radial surface 139 of the second flange outer ring 138, an inner block 154 mounted to the outer axial surface 127 of the drum plate 126, and a locking mechanism 156 such as a spring loaded plunger. The locking mechanism 156 may be affixed to the outer block 152 and is configured to releasably lock together the outer block 152 and the inner block 154.

The locking mechanisms 156 may be spring loaded plungers biased in the locked position, that is, the position in which the outer block 152 and the inner block 154 are locked together. When a user wants to unlock the second flange 116 so that it can rotate with respect to the drum 118 in order to, say, make a sharp turn, the user pulls or otherwise manipulates the spring loaded plungers 156 so that they are disengaged from the inner blocks 154 and thus in the unlocked position.

Third Embodiment

Referring to FIG. 9, a third embodiment 210 comprises a drum assembly 212, a first flange 214 and a second flange 216. One and preferably both flanges 214, 216 are rotatable. The flanges 214, 216 may be mirror images of each other and may be made of the same parts, rendering the reel 210 simpler to make. By making both flanges 214, 216 rotatable, the reel 210 may be held in place and the drum 218 can spin freely.

The drum assembly 212 comprises a large diameter drum 218, smaller diameter extensions 224 and drum plates 226. The drum 218 has opposing first and second ends 220, defines an axis A and is configured to receive wound product. The drum plates 226 are affixed to each of the first and second ends 20 and may have openings for receiving the drum extensions 224. The small diameter extensions 224 may be rigidly fixed to the drum 218 and extend axially outward from each of the first and second ends 220. The drum extensions 224 may be affixed to the drum plates 226 and may fit within the openings in the drum plates 226.

Each drum plate 226 may comprise an inner plate 227 and a preferably coplanar outer plate 229 and may extend radially outward from the drum 218 or from the drum extension 224 to the rim 232. The inner plate 227 may be affixed to the inside of the drum 218. The outer plate 229 may extend radially outward from the inner plate 227. The drum plate 226, including the inner plate 227 and the outer plate 229, allows for full protection of the wound product which cannot contact parts that are in rotation. Each drum plate 226 defines a plurality of small openings 241 preferably located in the inner plate 227 for receiving fasteners 246 as explained in more detail below.

As noted above each flange may be rotatable with respect to the drum 218. To achieve this, each flange 214, 216 may comprise a substantially cylindrical, low friction center ring or cylindrical member 228, spokes 230 and a rim 232. The flange cylindrical member 228 may be a cylindrical structure having an inner diameter slightly larger than the outer diameter of the drum extension 224 so that the flange 214, 216 can slide onto a drum extension 224 during assembly. The flange cylindrical member 228 may also be any structure that can be rotatably mounted to the drum extension 224, including for example a bearing assembly. The spokes 230 extend radially outward from the flange center ring 228 and have distal ends. The rim 232 is affixed to the distal ends of the spokes 230.

Each flange 214, 216 may further comprise a plurality of radially arranged, fastener receiving plates 240. Each fastener receiving plate 240 may be configured to fit between adjacent spokes 230. The fastener receiving plates 240 may be affixed, as by welding or other means, to the center ring 228 and/or the spokes 230.

A locking ring 244 may be slid over the drum extension 224 and welded or otherwise affixed thereto to secure each flange 214, 216 to the drum assembly 212. Sufficient play (gaps) should be left between the locking ring 244 and the flange center ring 228 and between the flange center ring 228 and the drum plate 226 to allow the flanges 214, 216 and/or drum 218 to rotate freely when the fasteners 246 are in the unlocked position.

Each fastener receiving plate 240 has at least one fastener opening 245 therein for receiving fasteners 246. When assembled, the fastener openings 245 in each fastener receiving plate 240 align with the plate openings 241 in the drum plate 226.

FIG. 10 is a perspective view of the reel of FIG. 9. The fasteners 246 may be bolts or, preferably, spring loaded pins. The fasteners 246 have two positions. In a first (locked) position the fasteners 246 extend through the openings 245 in the fastener receiving plates 240 and through the drum plate openings 241 to secure the each flange 214, 216 in stationary relationship with the drum assembly 212. In a second (open) position, the fasteners 246 do not extend into the drum plate openings 241, thereby allowing the flange 214, 216 to rotate with respect to the drum assembly 212.

Each flange 214, 216 can be locked in multiple positions with respect to the drum assembly 212 because of the multiple sets of openings 241 in the drum plates 226.

In a variation, in place of the openings 245 in the fastener receiving plates 240, holes may be formed in the spokes 230 and used to receive the fasteners 246, eliminating the need for the fastener receiving plates 240.

INDUSTRIAL APPLICABILITY

Thus there has been described a reel having two flanges in which one or preferably both flanges are rotatable with respect to the drum. The reel has solid plates on each end that protect the wound product so that it cannot contact parts that are in rotation. The flanges may be mirror images of each other to reduce the number of parts. Since both flanges are rotatable, the flanges can be held stationary leaving the drum free to spin, which allows the wound product to be unwound without rotating the entire reel.
